It is a short-toe traditional-grained slow speed film. I've got nothing against it, but I don't use it because I wasn't crazy about the highlights I got with it.

DISCLAIMER: I did not plot curves for Pan F. I do not plot curves for any film, although I do use step wedges for evaluating papers. I use TMY in LF because of its reciprocity characteristics. Sometimes I even use a red filter with TMY. I never used Super XX, and I'm not crazy about the work of the only Super XX fetishist I know personally. I also develop Azo in Dektol, use Wollensak wideangles, carry a monorail in the field, run with scissors, like COT320, and only use overexposed HIE in 35mm because I like the soft-focus look.
